# Ahrefs as a data source
> Bring data from Ahrefs to your Lakehouse.
Ahrefs is an SEO toolset that indexes the web to report on backlinks, organic and paid search performance, keyword research, rank tracking, and site audits. This connector reads the Ahrefs API v3 and brings those reports into your Lakehouse.
## Configuring Ahrefs as a Source
In the [Sources](https://app.nekt.ai/sources) tab, click on the "Add source" button located on the top right of your screen. Then, select the Ahrefs option from the list of connectors.
Click **Next** and you'll be prompted to add your access.
### 1. Add account access
You'll need an Ahrefs API key. In Ahrefs, go to **Account settings > API keys** and create one. Only workspace owners and admins can create API keys, and each key expires one year after it is created.
The Ahrefs API is available on eligible paid plans, and most reports consume **API units** from your monthly allowance. Read the cost section below before configuring the source.
The following configurations are available:
* **API Key**: your Ahrefs API key.
* **Targets**: the domains or URLs (for example `example.com`) to pull the Site Explorer reports for. One request is made per target per report. Leave this empty to skip every Site Explorer stream.
* **Keywords**: the keywords to pull the Keywords Explorer reports for. Leave this empty to skip the keyword streams.
* **Country**: (Default: `br`) the two-letter country code (ISO 3166-1 alpha-2) the reports are scoped to. It applies to every Site Explorer and Keywords Explorer report that accepts a country.
* **Row Limit per Report**: (Default: `1000`) the maximum number of rows fetched per report per target. Ahrefs bills API units per returned row, so this is the main lever on how much a sync costs.
Optionally, under advanced settings:
* **Start Date**: the earliest date to pull the historical reports from. It is only used on the first sync; afterwards each history stream resumes from its own bookmark. Defaults to one year ago.
* **Target Scope**: (Default: `subdomains`) how much of each target to report on - `exact` for that URL only, `prefix` for the URL and everything under it, `domain` for the domain without subdomains, or `subdomains` for the domain and its subdomains.
* **Protocol**: (Default: `both`) the protocol of the target to report on - `both`, `http`, or `https`.
* **History Granularity**: (Default: `daily`) the time interval used to group the historical reports - `daily`, `weekly`, or `monthly`.
* **Search Volume Mode**: (Default: `monthly`) how search volume is calculated - `monthly` for the latest month, or `average` for the average of the last 12 months.
Once you're done, click **Next**.
### 2. Select streams
Choose which data streams you want to sync. For faster extractions, select only the streams that are relevant to your analysis. You can select entire groups of streams or pick specific ones.
> Tip: The stream can be found more easily by typing its name.
Select the streams and click **Next**.
### 3. Configure data streams
Customize how you want your data to appear in your catalog. Select the desired layer where the data will be placed, a folder to organize it inside the layer, a name for each table (which will effectively contain the fetched data) and the type of sync.
* **Layer**: choose between the existing layers on your catalog. This is where you will find your new extracted tables as the extraction runs successfully.
* **Folder**: a folder can be created inside the selected layer to group all tables being created from this new data source.
* **Table name**: we suggest a name, but feel free to customize it. You have the option to add a **prefix** to all tables at once and make this process faster!
* **Sync Type**: you can choose between INCREMENTAL and FULL\_TABLE.
* Incremental: every time the extraction happens, we'll get only the new data - which is good if, for example, you want to keep every record ever fetched.
* Full table: every time the extraction happens, we'll get the current state of the data - which is good if, for example, you don't want to have deleted data in your catalog.
Once you are done configuring, click **Next**.
### 4. Configure data source
Describe your data source for easy identification within your organization, not exceeding 140 characters.
To define your [Trigger](https://docs.nekt.com/get-started/core-concepts/triggers), consider how often you want data to be extracted from this source. This decision usually depends on how frequently you need the new table data updated (every day, once a week, or only at specific times).
Optionally, you can define some additional settings:
* Configure Delta Log Retention and determine for how long we should store old states of this table as it gets updated. Read more about this resource [here](https://docs.nekt.com/get-started/core-concepts/resource-control).
* Determine when to execute an **Additional [Full Sync](https://docs.nekt.com/get-started/core-concepts/types-of-sync#additional-full-sync)**. This will complement the incremental data extractions, ensuring that your data is completely synchronized with your source every once in a while.
Once you are ready, click **Next** to finalize the setup.
### 5. Check your new source
You can view your new source on the [Sources](https://app.nekt.ai/sources) page. If needed, manually trigger the source extraction by clicking on the arrow button. Once executed, your data will appear in your Catalog.
For you to be able to see it on your [Catalog](https://app.nekt.ai/catalog), you need at least one successful source run.
## API units and sync cost
Ahrefs meters most of its API. A request costs `max(50, per_row_cost x rows)` API units, where `per_row_cost` is the sum of the unit cost of every column requested - 1 unit by default, and 5 or 10 units for premium metrics such as search volume, traffic, and keyword difficulty. The field descriptions below name the premium columns explicitly.
Three things control how much a sync costs:
* **Row Limit per Report** caps how many rows each report returns. Reports are ordered by their most meaningful metric, so the rows kept are the most relevant ones.
* **Stream selection** decides which reports run at all. The Rank Tracker, project management, and subscription streams are free; the Site Audit issues report costs a flat 50 units per project.
* **Column selection** is passed through to Ahrefs. Columns you deselect are not requested, so they are not billed.
The units actually consumed appear in the run logs, and the `subscription_limits_and_usage` stream records your remaining monthly allowance on every sync.
You can also cap the monthly usage of an individual API key in Ahrefs under **Account settings > API keys**, which is a useful safety net while you tune the configuration.
## Limitations
* **No pagination.** Ahrefs API v3 accepts a row limit but offers no way to request a next page, so each report returns its top rows only. Raise the row limit if you need more, keeping the unit cost in mind.
* **Rate limit.** Ahrefs allows 60 requests per minute. The connector paces itself below that limit, so syncs with many targets take proportionally longer.
* **Reports outside your plan.** Endpoints your subscription does not cover are skipped with a warning instead of failing the run.
* **Adding a target later.** History streams keep one bookmark per stream rather than one per target. If you add a target to an existing source, run a full sync to backfill its history.
